"Hmm..."
When the heavy solid wooden board was opened, a cloud of smoke and dust rose up.
Sakaki waved his hands to disperse the smoke and dust, and looked intently...
The clothes were completely burned, the body was curled up into a ball, the arms were raised high, the internal organs were exposed, the part below the knees was completely shattered, and it was as black as if it was splashed with ink. The surface skin was burned away, and even the muscle tissue underneath was carbonized.
The only thing that was still intact was the eye-catching white ribs.
“How miserable…”
Hattori Heiji whispered:
"Even if you are in a fire, it shouldn't burn so thoroughly. It's like, it's like..."
“It’s like being cremated.”
Conan continued the second half of his sentence.
Being burned to death is definitely one of the most painful ways to die.
Bang!
Putting on gloves, Makoto Sakaki knelt down and stretched out his palms...
Snap...
The almost completely carbonized corpse couldn't even withstand his light touch and broke into pieces.
"It's troublesome..."
Sakaki Makoto frowned.
The body was burned to this extent, and it was very difficult to find any clues from it.
Fortunately...
Because the body was curled up, the internal organs were protected by the ribs and the damage was not serious.
This is also one of the few ways to obtain clues.
It's a blessing in disguise.
"Don't do it..."
Makoto Sakaki stopped Miss Miyano who wanted to perform an autopsy:
"I'll do it."
His eyes were extremely serious. Miss Miyano hesitated for a moment but did not intervene.
Sakaki Makoto tried his best not to let Miss Miyano come into contact with a corpse that had died in such a painful way.
It's fine to just wait and see, but if an autopsy is performed...
This is bound to cause serious psychological burden to Miss Miyano.
Some pressure...
He just has to bear it alone.
Laying the corpse face up, Makoto Sakaki carefully opened the corpse's eyelids...
The lens is serious, or...
It has dried up into a sticky substance.
Sakaki Makoto's expression became even more serious.
He then examined the head and hips of the corpse, measuring their length...
"The body is 95cm long, male."
Prying open the mouth of the corpse, Conan turned on the flashlight to illuminate the mouth of Makoto Sakaki...
"The teeth have smoke stains, and there is a little carbon ash on the lips, tongue, and throat, and there are burn marks."
Without professional tools, Makoto Sakaki could not determine the age of the corpse by looking at its teeth.
but...
He picked up the key that had fallen beside the body and looked at it in the light.
"This is..."
The old principal who was watching his every move from behind suddenly said:
"The key to the gym warehouse!"
"Um...."
With a serious expression, Sakaki Makoto said word by word:
"Mr. Uematsu, is there any adult missing in the school?"
The old principal reacted immediately and said to the secretary beside him:
"Go check who is missing from our school."
"yes."
The secretary hurried out of the warehouse, found two assistants, and checked each classroom one by one...
About 15 minutes later...
Ta-da-da...
"headmaster!"
The secretary came back in high heels:
"Teacher Ota from the health room is missing!"
"Can I get through to him on the phone?"
"I tried it, it doesn't work!"
"This Mr. Ohta you're talking about, is he using a Samsung flip phone?"
The old principal and the secretary looked down...
Conan came over with a phone with an exploded battery and a shattered screen, leaving only an empty shell:
"I just found this in the ruins."
Seeing the Samsung logo on the empty shell...
The old principal closed his eyes and nodded sadly:
"I didn't expect that Mr. Ota Kunimatsu would actually...Ah!"
His eyes flashed, and Sakaki Makoto noticed something was wrong.
The teacher in the health room...
Why did he come to the gymnasium alone with the key to the gymnasium warehouse?
Why didn't he escape when the fire broke out?
What was the cause of the fire?
Hattori Heiji had the same question as him. While waiting for his secretary to come back, he went to ask the fire department and learned...
"The fire was probably caused by sparks igniting the mats in the sports warehouse."
The idea of burning corpses to destroy evidence is not groundless.
Among the countless cases that Makoto Sakaki has encountered, fire scenes are definitely the most difficult to investigate, no doubt about it.
When a fire occurs, it only takes 10-15 minutes for the temperature of the fire scene to rise to 400°C. If people in the fire area cannot evacuate in time at this time, they will be poisoned by smoke, suffocated, or even scalded or burned to death.
This is just the temperature when the fire just started.
If there are common organic materials in the fire scene, such as cloth, wood boards, etc.
Taking a closed gymnasium as an example, the flames, hot air layers and walls will quickly accumulate heat, and eventually return the heat to the combustibles by convection and radiation, thereby intensifying the gasification (thermal decomposition) and combustion of the combustibles.
Especially radiant heat, strong radiation will pose a great threat to nearby buildings. When the radiant heat reaches a certain level, combustibles far away from the fire will also be ignited, further intensifying the fire. This interaction is also called...
Explosion.
Once the flashover mode is entered, the temperature at the fire scene will surge from 400-500°C to 800-900°C, and the local temperature can even reach as high as 1100°C. This is related to the type of combustible materials at the fire scene.
